A series of copper coordination polymers of [Cu-3(OH)(2)(5-iipa)(2)(phen)(3)(H2O)center dot 4.5(H2O)](n) (1) [Cu(5-iipa)(phen)(H2O)](n) (2), [Cu(5-iipa)(bpe)center dot 2(H2O)](n) (3), [Cu(5-iipa)(p-bix)](n) (4), [Cu(5-iipa)(bbi)](n) (5), [Cu-2(5-iipa)(2)(bbi)center dot 0.5(H2O)](n) (6), and [Cu(5-iipa)(bpp)center dot H2O](n) (7) (phen = 1,10-phenanthroline, bpe = 1,2-bis(4-pyridyl)ethane, p-bix = 1,4-bis(imidazol-1-ylmethyl)-benzene, bbi = 1,1'-(1,4-butanediyl)bis(imidazole), bpp = 1,3-bi(4-pyridyl)propane) were hydro(solvo)thermally synthesized through the reaction of divalent copper salts, 5-iodo-isophthalic acid (5-H(2)iipa), and N-donor ancillary ligands. Single-crystal X-ray diffraction analyses on these complexes revealed that noncovalent interactions were found to be predominant in constructing these supramolecular architectures. Compounds 1-5 all possess three-dimensional (3D) supramolecular structures based on O center dot center dot center dot I, I center dot center dot center dot I, I center dot center dot center dot pi, and pi...pi interactions. Compound 6 exhibits a complicated three-dimensional (3D) framework with a new (6.7(2))(2)(6(3).7(2).8)(2)(6(3).7(8).8(2).9(2)) topology, while 7 features a 3D 3-fold interpenetrating network with a (4,4)-connected (3.8(5))(3(2).8(3).9) topology. A systematically structural description of these polymers indicates both halogen-related interactions and N-donor auxiliary ligands have a significant effect on the coordination network assembly. Their thermal analysis, X-ray diffraction, and UV-vis absorption spectra have also been investigated as well.
